About Me

I am a third year PhD candidate with Prof. Dinesh Bharadia at UCSD. I design and implement novel algorithms for wireless communication and sensing with a focus on millimeter-wave system, vehicular communication, and virtual reality. We built a mmWave testbed at 28 GHz to evaluate and address user mobility challenges at these frequencies. Apart from research, I enjoy working with student organizations, organize campus-wide events and often visit nearby hiking trails. Please feel free to explore my webpage and connect with me.

Research Projects

project name mmReliable

Two beams are better than one: Towards Reliable and High Throughput mmWave Links [Sigcomm'21]

We build mmReliable, a reliable mmWave system that implements multi-beamforming and user tracking to handle environmental vulnerabilities. It creates constructive multi-beam patterns and optimizes their angle, phase, and amplitude to maximize the signal strength at the receiver. Multi-beam links are reliable since they are resilient to occasional blockages of few constituent beams compared to a single-beam system. Rigorous indoor and outdoor experiments on our mMobile platform demonstrate that mmReliable achieves close to 100% reliability.

project name mMobile

mMobile: Building a mmWave Testbed to Evaluate and Address Mobility Effects [mmNets'20]

We built a custom 5G NR compliant mmWave testbed at 28 GHz to evaluate beam management algorithms. We describe the architecture and challenges in building such a testbed. We then create a novel, low-complexity beam tracking algorithm by exploiting the 5G NR waveform structure and evaluate its performance on the testbed. The algorithm can sustain almost twice the average throughput compared to the baseline.

project name LocAP

LocAP: Autonomous Millimeter Accurate Mapping of WiFi Infrastructure [NSDI'20]

LocAP is an autonomous system to physically map the environment and accurately locate the attributes of existing wireless infrastructure in the physical space down to the required stringent accuracy of 3 mm antenna separation and 3 degree deployment orientation median errors, whereas state-of-the-art algorithm reports 150 mm and 25 degree respectively.

mmWave Blockage Analysis

We analyze the impact of blockage by static buildings, mobile blockers as well as self-blockage by the user's body. Our results indicate that the minimum density of BS required to satisfy the Quality of Service (QoS) requirements of Ultra Reliable Low Latency Communication (URLLC) applications is mainly driven by reliability and latency constraints, rather than coverage or capacity requirements.

Work Experience

Summer Research Intern
Nokia Bell Labs, Murray Hills, NJ (May - Aug 2017)

Mentor: Ozge Kaya
Developed beam training algorithm for initial access in mmWave Network. It allows the users to connect to the mmWave access point faster than the traditional exhaustive search scheme using directional beams. The algorithm is robust to channel variations, blockages, and user's mobility.

MITACS Research Intern
University of Victoria, Canada (May - Jul 2015)

Mentor: Dr. Jianping Pan, Dept. of Computer Science
Studied state-of-the-art Rendezvous algorithms for Cognitive Radio Networks and obtained channel availability probability for cognitive users based on primary users location in a cellular model, which is used to evaluate the rendezvous performance in the practical conditions.
